Tired of writing this: this painting is not some culturally important piece of art. It's a little over 100 years old, hanging in a university, of a man that was responsible for massacres in Ireland (Mitchelstown Massacre) which got him the name "Bloody Balfour". Regardless of where you stand on Palestine, Balfour was not a good human and this is akin to toppling a minor statue of a Confederate in America - one that is not even on display to the wider public.
EDIT to add a quote from Balfour when asked about whether the treatment of Black people in South Africa was immoral:
“We have to face the facts,” Lord Balfour said. “Men are not born equal, the white and black races are not born with equal capacities: they are born with different capacities which education cannot and will not change.”
